The third limiting member is disposed on a first side of the second rotating wheel 420 opposite to the second side thereof. The third limiting member specifically includes a third main limiting member 422 and a third sub limiting member 423, where the third main limiting member 422 and the third sub limiting member 423 are both bumps, and are disposed on the outer periphery of the surface of the first side at a predetermined distance. Correspondingly, the bottom plate 110 is provided with a first limiting member 112 and a second limiting member 113, and the first limiting member 112 and the second limiting member 113 are both convex columns. The third main limiting member 422 is used for abutting and matching with the first limiting member 112, and the third auxiliary limiting member 423 is used for abutting and matching with the second limiting member 113.
A limiting groove 424 is further formed in the middle of the surface of the first side of the second rotating wheel 420.

The lifting assembly 400 is disposed on the upper surface of the base plate 110 and around the through hole 111. The supporting wheel 440 is disposed on the bottom plate 110 and located between the through hole 111 and the lifting assembly 400, one end of the flexible rope 300 is connected to the hanging member 211, and the other end of the flexible rope passes through the supporting wheel 440 and then winds around the second wheel 420.

And S20a, executing corresponding operation according to the control signal.
When the control signal is a lifting signal, the motor 430 is controlled to rotate forward in a first direction, so that the first rotating wheel 410 drives the second rotating wheel 420 to rotate forward, and the flexible rope 300 drives the cleaning assembly 200 to move upward to lift the cleaning assembly 200. When the third main limiting member 422 abuts against and engages with the first limiting member 112, the cleaning assembly 200 is lifted to a predetermined position. At this time, when the motor 430 is controlled to stop the forward rotation, the cleaning assembly 200 may be maintained at the preset position, thereby maintaining the lifted state. When the motor 430 is controlled to continue to rotate forward, since the third main limiting member 422 abuts against the first limiting member 112 for limiting and is provided with a spring, the second rotating wheel 420 moves to one side of the spring under the driving force of the first tooth portion 411 and moves to one side of the first rotating wheel 410 again under the elastic force of the spring, so that the second tooth portion 421 and the first tooth portion 411 generate tooth skipping, and the cleaning assembly 200 is maintained at the preset position, thereby maintaining the lifted state. That is, after the cleaning assembly 200 is lifted up to the position, the cleaning assembly 200 is maintained at the predetermined position regardless of whether the motor 430 stops the forward rotation or continues the forward rotation, thereby maintaining the lifted state.

When the third sub-limiting member 423 abuts against and is matched with the second limiting member 113, the cleaning assembly 200 falls back to the initial position. At this time, when the motor 430 is controlled to stop the reverse rotation, the cleaning assembly 200 may be maintained at the initial position, thereby maintaining the reset state. When the motor 430 is controlled to rotate reversely, since the third sub-stopper 423 and the second stopper 113 are abutted against each other for stopping and are provided with a spring, the second wheel 420 moves to one side of the spring under the driving force of the first tooth 411 and moves to one side of the first wheel 410 again under the elastic force of the spring, so that the second tooth 421 and the first tooth 411 jump and the cleaning assembly 200 is maintained at the initial position, thereby maintaining the reset state. That is, after the cleaning assembly 200 falls back into position, the cleaning assembly 200 is maintained at the initial position regardless of whether the motor 430 stops or continues to rotate reversely, thereby maintaining the reset state.
